In an excerpt of her new-brand memoir, Giuliana Rancic reveals Jerry O’Connell cheated on her at least two times.

After meeting at the W Hotel in San Diego, Giuliana Rancic and Jerry O’Connell developed a special bond that quickly turned into something romantic.

After a while, Giuliana Rancic found out Jerry O’Connell was cheating on her with Spice Girls member Geri Halliwell.

“I was being two-timed…?” the E! News co-anchor wrote in her new book per Page Six before detailing Jerry O’Connell’s reaction.

“<<Yeah, I know. I’m so sorry. I don’t know what happened.>> He has as much emotion as the customer-service representative who tells you your bags missed the flight.”

Giuliana Rancic proved she was willing to forgive when she gave the relationship a second chance. But when attending Maxim’s 100 Hottest Women Party in 2004, she spotted Jerry O’Connell getting flirty with Rebecca Romijn.

“Little did I know he was in the VIP area, talking to Rebecca,” Giuliana Rancic dished.

“As a prelude to feeling up Rebecca.”

In a matter of days, Jerry O’Connell stopped taking Giuliana Rancic’s phone calls before she eventually decided to confront him at home.

“Nope. Sorry, homegirl,” Jerry O’Connell said while ending the relationship for good.

“Things change, but you take care, OK?”

For those keeping track, Jerry O’Connell and Rebecca Romijn ended up getting married in 2007. They have three kids together. Giuliana also married Bill Rancic the same year.
